X-Plane's most popular and best-selling add-on is back as version 4.0, and with some stellar new features!

Maxx-XP, in co-operation with Sundog Software, and X-Aviation are excited to bring you another game changing experience to the weather rendering in X-Plane 10 and X-Plane 11! SkyMaxx Pro v4 is an X-Plane cloud and sky replacement engine boasting all-new technology for X-Plane that it's almost like having an all-new sim!

NEW: SkyMaxx Pro v4.9+ now supports Vulkan for X-Plane 11.5+! For Mac users, SkyMaxx Pro v4.9+ can still be ran when using OpenGL mode in X-Plane's rendering settings. Metal is not supported.
NEW FSGRW Integration!: The FS Global Real Weather engine is now able to process a wide variety of cloud identifiers, such as Cirrus, Cumulus, Stratus, Cumulonimbus and Towering Cumulus. Cirrocumulus, Nimbostratus and Stratocumulus depiction in X-Plane 11 is planned for the near future. This detailed, cloud specific information is passed onto Real Weather Connector, allowing SkyMaxx Pro v4 cloud types and their corresponding cloud textures in X-Plane 11 to be correctly interpreted and drawn for different altitude levels, while at the same time FS Global Real Weather injects real-time wind data into X-Plane 11. This adds a highly sophisticated level of realism to the X-Plane 11 world, and greatly enhances the immersive environment for both low-level GA flyers and high-altitude airline pilots.Developer: Maxx-XP Download Size: 120MB

How SkyMaxx Pro works
SkyMaxx Pro is a plug-in that disables X-Plane's cloud and weather rendering engine, then replaces it with the SkyMaxx Pro version of weather. It takes weather data from the already existing X-Plane weather menu that you are used to, so there's nothing new to learn. What you gain are some amazing visual effects at almost no performance hit! In fact, most of our test team showed that when running default X-Plane clouds vs. SkyMaxx Pro clouds, SkyMaxx Pro had better frame rates over the default X-Plane clouds!

New features in Version 4.0:

Designed to work with both X-Plane 10 and 11!
- Code is implemented in SkyMaxx Pro v4 to know whether you are running X-Plane 10 or 11. Depending on which version, SkyMaxx Pro auto adjusts for the version of X-Plane you are running!

Double your maximum cloud draw area compared to SkyMaxx Pro v3!
- Big performance improvements allow clouds to be drawn across an area up to 320 km across surrounding your plane. Go ahead and crank up SMP's cloud draw area setting and achieve fast, realistic scenes at FL300 and above.

New 3D precipitation system!
- The new precipitation system represents rain, sleet, wet snow, and dry snow - as well as mixed precipitation that responds automatically to the ambient temperature. Precipitation is even lit by your landing lights! And a whole new precipitation control panel lets you tweak its appearance to your own liking.

Precipitation is tied to individual clouds
- Rain will start and stop realistically as you fly underneath or through the clouds
